On-air promotions for next week’s Offspring reveal that Nina is a potential donor — but that it comes with significant risk.

Ten’s publicity blurb states: “Another Proudman life hangs in the balance. Little Alfie urgently needs a transplant and the family band together to support Zara and Jimmy in their frantic search for a donor.

“Nina faces a huge dilemma. She is a suitable candidate, but will she put herself in danger and Zoe at risk of losing another parent to save Alfie’s life.”

Earlier this year Keddie made a point of reassuring fans that Offspring wouldn’t be all doom and gloom this season.

“It (series five) is really positive even though the characters are not without their difficulties,” Keddie said.

“For me, it is the most honest series that we’ve shot.

“We had to think a lot about the message we wanted to put out there. Although life can be really difficult it can be really inspiring, and that has a lot to do with the people you surround yourself with.”
